New Sky channels: Crime, Comedy, Documentaries, Nature

We don't know.

E and SyFy are carrying on screen messages that they are moving to 151 and 152 on 27th May.

Any indication of what’s happening to Challenge?

I wouldn't be surprised if Pick and Challenge moved to 159 and 160.

Pick is already on 159 in the Channel Islands and nothing is on 159 or 160 anywhere in the UK so moving them here seems the obvious choice.

History has reported its strongest month in nearly 7 years, a week ahead of the rebrand

Slightly off-topic, apologies, but why isn't Pick on 152 in the Channel Islands?

That's odd

Yeah, it is odd. 152 appears to be unoccupied there, and 159 is unoccupied everywhere else, so that doesn't make sense.

Pick will be on 159 everywhere from May 27th.

New channel numbers:

114 - Sky Documentaries
123 - Sky History
130 - Sky Nature
151 - E!
152 - SYFY
159 - Pick
160 - Challenge

159 (and 160) were previously owned by Viacom and used for 5Select and VH1. Both became empty in January when 5Select moved to 153 and VH1 closed. Sky bought the slots but had to use them, as an EPG slot is lost if it isn't used within a certain timeframe.

Pick was put on 159 in the Channel Islands to keep that slot active, and Viacom's Smithsonian had a very short spell on 160 to keep that alive.

That would explain why channels like Sky 2 have been kept, rather than being closed to make way for the new channels.
